Permeability causes more problems in the real world than almost anything else – with costs running into the billions each year in the UK alone. It causes food to rot, damp in buildings, industrial processes to fail, things to leak and electronics (and even missiles) to fail.
We have launched a fast and accurate way to measure this in precise, temperature controlled conditions. The way water vapour leaches into buildings varies considerably with how cold or hot it is outside, and semi-permeable filters are crucial in a wide range of industrial processes at temperatures that can vary up to and beyond 1000 C.
Our latest equipment can optionally measure this this across a very wide temperature range for "leakage" of virtually any gas or vapour. It can also measure almost any material – including cmplete components, complete units and finished structures.
Vapour permeability measurements are widely used in almost every industry as it is critical in most real-life applications. It substantially alters properties such as the shelf-life of pharmaceuticals and packaged foods, the efficiency of pipelines, seals and valves and even the waterproof-ness of paints and coatings.
Our range of sensors, use a wide range of physical principals and enable the equipment to be used across an unprecedented variety of applications to characterise an ever expanding range of materials, compounds, containers, products and laminates. Temperatures can range from around up to around 1300 C.
The permeability meters are highly automated and can cope with several samples at a time. It needs very little re-calibration and requires, at most, minimal training. Sensitivities depend on sensors, gases and materials but are usually in the PPM (Parts Per Million) range, PPB for some materials. Results are both accurate and highly repeatable.

Vapour permeability is the measure of how strongly a material can resist the barrier passage of any gas (such as water vapour, Oxygen, CO2 or a hydrocarbon). Vapour permeability dramatically affects the physical characteristics of most products and materials, from outdoor clothing to missiles and from pizza to industrial seals.
